Side Angle Side Postulate
Proving Congruent Triangles with SAS
The Side Angle Side postulate (often abbreviated as SAS) states that if two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then these two triangles are congruent.
The included angle means the angle between two sides. In other words it is the angle 'included between' two sides.
